Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm is a right triangle?
the triangle is a right triangle because 5^2 + 12^2 = 13^2.
the triangle is not a right triangle because 5 + 13 > 12.
the triangle is not a right triangle because 5^2 + 13^2 > 12^2.
the triangle is not a right triangle because 5 + 12 > 13.

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
